Topological two-body bound states in the interacting Haldane model
Topological two-body bound states in the interacting Haldane model
We study the topological properties of the two-body bound states in an interacting Haldane model as a function of interparticle interactions. In particular, we identify topological phases where the two-body edge states have either the same or the opposite chirality as compared to single-particle edge states. We highlight that in …
